Your PCa seems to be taking an unusual path but you have thought things through and as you say if it gets get really bad, you have the enlightened assisted dying in OZ. Unfortunately, in the UK Parliament has talked a lot about it then it gets put on the back burner like so many other questions they don't want to answer. My wife died of dementia, pneumonia and starvation last year, When I visited her in the care home I could hear her screaming before I even got to her room. This continued throughout my visit and after I left until exhausted she fell asleep. Had assisted dying been provided in the UK, she would have not have had to endure several weeks of pain and anguish. PCa can also be a rotten death and whether it's because of this or something else, I hope the Bill will be enacted here soon.
